Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Emese Revfy discovered that in the Linux kernel signal handlers could leak address information across an exec, making it possible to bypass ASLR (Address Space Layout Randomization). A local user could use this flaw to bypass ASLR to reliably deliver an exploit payload that would otherwise be stopped (by ASLR). (CVE-2013-0914)

A memory use after free error was discovered in the Linux kernel's tmpfs filesystem. A local user could exploit this flaw to gain privileges or cause a denial of service (system crash).
(CVE-2013-1767)

Mateusz Guzik discovered a race in the Linux kernel's keyring. A local user could exploit this flaw to cause a denial of service (system crash). (CVE-2013-1792).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
